This invention relates t -cutt-ingor ornamenting dies and has special reference toa holder forfsuch-dies and equipment in connection with the holder permitting selective attachment and removal of the dies." 1

Q An object of the invention is to provide a die-for cutting or ornamenting purposesand a holder forsaid die having a locking or latching device adapted toengage withportions of thedie in ordertohold the die in fixed relationship to the-holder and to permit easy removal ofthe die.

v p Another objectof the invention is to provide an improved die'holder and means, tor supporting same for longitudinal sliding movements, vice in connection with the holder for en'gag ing portions of a cutting or'ornamenting die so as to support 'thedie'in connection with the holder whereby the die will be moved by p y of the cap n orderto permit removal ofthe and with the holder.

from the followingdescription, reference being made to the accompanying drawings in which I have illustrated anappropriate embodiment of the invention and in which V a Fig. 1 is-a side elevation ofthe die in con 7 nection with, the' holder, a; portion of the holder and the carrier therefor being in sec-.

in combination with a latch de l The hoider which is mounted in the carrier comprisesa head 4 having a-polygonal stem 5 projecting forsliding I movements through thehole in the lower end of the socket 2 and I thenceupwardly into the socket. Thus the polygonal stein which is mounted for sliding movementsin the similarly shaped hole in the d carrier willhold the head from turning and thuswill guide and operate the die in precisely the same.relationshiptothe carrier at each operation. A cap 6 encloses the upper end of the stem 5 and extends downwardly into the socket Qand cooperates with that,

portion of the stem which is in the polygonal H hole at the lower end of the socket to guide the die holderin a straight line and to prevent oscillation of the die holder. A removable pin 7 extends through the stem 5 and the enclosing walls of the cap 6 and secures these 7 parts together but provides for detachment die holder irom the die carrier; A spring 8 is mounted in the socket 2 and has its lowe'r end seated upon the flange 3 and its upper end seatedagainst the lower end of the cap 6. This'spring 8 is a' coil spring and encircles the stem 5 and the resilient powerand energy of said "springis effective to support the die holderlin its idle orstarting position in which the upper end ofthe head 4 is in abutting contact with the lower end of the socket 2. Said spring alsopermitsdownward sliding'movemerit of the die holder by any appropriate actuator or driver andis effective to move the die holder to its idle or starting position" after each operation.

The head 4 is uniform diameter throughout its length but in this regard the"formation of the socket may sect and open into diametrically opposite sides of said socket I I V The cutting. or ornamentlng tile shown comi prises aheadl3 equipped on its lower end formed with a diametrical" 7 socket 9 which be and preferably isof with a cutting or ornamenting device 14. In the case of the cutting die, the head 13 may be hollow, that is to say, said head may have therethrough a hole or passage 15 for the reception and movement of the waste material thatis cut by the die from the work. The head 13 is connected by a number of spaced arms 16 with an end portion 17. Two spaced pins 18 project rigidly from the die end 17. These pins are spaced apart the same distance as are the sockets 12 and are of approximately the same diameter as said sockets so that they may be inserted into and withdrawn from the sockets 12. Thus in order to attach the die to the holder the pins 18 are inserted into the sockets 12 until the upper wall of the die end 17 abuts against the lower wall of the holder head 4. Each pin 18 has on its inner side a rounded notch 19 formed on a radius of curvature of the same length as the radius of the socket 9. Thus when the pins 18 are within the sockets 12 and the die end 17 abuts against the lower end of the holder head 4 the walls of the notches 19 are flush and in alinement with the wall of the socket 9.

A latch or locking device for securing the die to the holder is mounted in the socket 9. This latch or lock device comprises an outer end portion 20 of approximately the same diameter as the socket 9 and which fits within the end of the socket 9 for sliding movements. This locking or latching device further comprises a coaxial elongation 21 of reduced diameter which fits within and projects through the hole 10. A screw 22 is en aged in a threaded hole in the end of the re uced portion 5 of the lock or latching device and the head of said screw constitutes an abutment designed and adapted, to engage against the wall 10 to prevent withdrawal of the locking or latching device from the die holder. On the reduced portion 21 a circumferential flange or collar 23 is arranged in such position and relationship that when the screw 22 is against the wall 10 said part 23 will engage and seat within the notches 19. That is to say, the diameter of the collar or flange 23 is approximately the same as the diameter of the socket 9- which is the same as the distance from the bottom of one of the notches 19 to the bottom of the other notch 19. Accordingly, when the die is in connection with the die holder and the a collar or flange 23 engages in the notches 19 of the pins 18, the die is supported in rigid connection with the die holder; the die holder is held from rotation in the manner described; and the die is held both from turning movements with respect to the die holder by the pins 18 and is held from longitudinal movements with respect to the die holder by the engagement of said pins with the collar or flange 23.

A spring 24 is mounted on the reduced portion 21 of the locking or latching device and has one end abutting against the socket end wall 10 and the other end abutting against the collar or flange 23. The power and energy of said spring is utilized effectively to hold the locking or latching device in position in which the head of the screw 22 is against the wall 10 and in which the collar or flange 23 is in looking or latching engagement with the pins 18, being engaged in the notches 19. The projecting end of the part 20 of the locking or latching device constitutes a handle or button for manual engagement by which said locking or latching device may be moved in opposition to the spring 24 and in a direction and to an extent to disengage the collar or flange 23 from the pins 28 so as to permit detachment of one die and substitutlon of another.

From the foregoing it must be apparent that I have provided an improved die holder which is designed and adapted to receive and support any selected ones of various interchangeable dies. The manner of attachment and detachment is highly simplified and the devices comprising the invention are well designed for their intended uses and functions. I am aware that the construction, arrangement and relationship of the parts may be varied within equivalent limits without departure from the nature and principle of the invention.
